Cosmas Indicopleustes, on 1Cor 15:50

“Now this I say, brethren, that flesh and blood cannot possess the kingdom of God: neither shall corruption possess incorruption.”

“For this the Apostle shows when he says: Flesh and blood cannot inherit the kingdom of God; here by the word flesh meaning mortality, and by blood mutability. He declared therefore that it is impossible for one who is mortal or mutable to inherit the kingdom of heaven. He subjoins immediately: Neither doth corruption inherit incorruption—and he repeated this, by way of showing that nothing that is corrupt can go up and enter there, for harm rather than any advantage would result. For just as we, who are far away from the sun, have not the power, should we direct our eyes to his disc, to continue doing so, but would be injured and blinded rather than profited, so would it fare with any one if, while still mortal or mutable or corruptible, he should seek to overstep the boundaries, and approach the way which leads to the kingdom of heaven, while still far off therefrom.”
